Abstract
The possibility of using various methods of biotesting together with chemical-analytical methods for the ecotoxicological assessment of waste from the oil industry (drilling sludge) and contaminated soil cover of objects of accumulated environmental damage located in the north-west of Russia is considered. Ecotoxicological studies by biotesting methods have been carried out using test organisms from different systematic groups. Conventional and proprietary biotesting methods were used. The proposed set of biotest systems for the purposes of environmental control of such objects along with chemical and analytical methods may increase the reliability of the research results.
